PURPOSE:To facilitate the installation of a device in a relatively shallow liquid tank, by a method wherein a multitude heat exchanger is disposed under the tail tube of a pulse burner, and exhaust gas delivered from the tail tube of the pulse burner through a decoupler is fed into the multitube heat exchanger. CONSTITUTION:A combustion chamber 12 of a pulse burner is disposed to the one side of a liquid tank 11, and an exhaust cylinder 14, joined with the end part side thereof, is coupled to the one end of a tail tube 16 through a coupling member 15. The other end of the tail tube 16 is coupled to a decoupler 17. The one end of each of plural first tube bodies 18 is coupled to the low end of the decoupler 17. A multitube heat exchanger 19 is formed with a plurality of second tube bodies 22 for heat exchange located in juxtaposition with each other between first and second headers 20 and 21, and is disposed below the tail pipe 16. Further, the one end of an exhaust pipe 23 is coupled to the second reader 21. As noted above, since a device is constituted such that exhaust gas, delivered through the tail tube of the pulse burner by means of the decoupler, is fed into a multitube heat exchanger, each constitution device may be disposed in a compact manner and can be easily installed even in a shallow liquid tank. |
